Photo Research Introduces the PR-730/735 SpectraScans
Photo Research has announced the introduction of its latest instruments, the
PR-730/735 SpectraScans. These products are the latest in the SpectraScan
series and feature a full color touch screen display, USB, RS232 or Bluetooth wireless
interfaces, up to 8 measuring apertures and selectable bandwidths. The PR-730 is
designed to cover the visible spectrum from 380 nm to 780 nm while the PR-735 measures
from 380 nm to 1100 nm for near-IR applications.
"The SpectraScan series is used extensively in the automotive and aerospace industries
because of the ability to measure small areas at low intensity levels. The PR-730/735
is better suited to these applications because of the 10X sensitivity improvement
over the nearest relative, the PR-705/715." The new PR-730/735 products,
like all Photo Research photometers and spectroradiometers, are unique in that they
can be configured to address virtually all light measurement applications without
changing instruments.

Introducing the New Photo Research 2-in-1 Ultra Low-Light
SpectraScan Duo
We are proud to announce the PR-680L SpectraDuo. Although
similar to the PR-680 in almost every way, the
PR-680L has a very important distinction - sensitivity. As you know the
PR-680 is actually two instruments in one - a 256 detector
spectroradiometer, and a PMT based filter photometer. In the case of the
PR-680L, the PMT instrument side is over 14 times more sensitive than that
of the PR-680. This means that this instrument is even more
attractive for customers who want a total display measurement solution - it provides
a greater capability for the hard to measure dark side of display contrast measurements.
The total PMT dynamic range including all apertures is a staggering 360,571,400:1
with the automated internal ND-1 filter. The system dynamic range is 0.00007fL ti
5,000,000 fL.

The all new PR-805, PR-810 and
PR-810L Pritchard Photometers
We are pleased to introduce the PR-8XX series of instruments. The PR-805, PR-810
and PR-810L instruments are PMT based, have individually trimmed photopic filter,
share the same packaging as the PR-655 / PR-670 / PR-680 including the full color
touch screen display, USB, optional RS-232 & Bluetooth Interface, SD card
measurement storage, and long lasting Li-ion battery. All three instruments feature
an optional 3µs fast response analog output. They all have the following internal
automated neutral density filters. ND-1, ND-2 & ND-3. The PR-805 is a single aperture
system. The PR-810 and PR-810L each have four automated apertures standard. The
PR-810L is a low level capability version of the PR-810 and can measure as low as
0.000003 cd/m² with a dynamic range of 512,000,000,000:1.

The New Photo Research 2-in-1 SpectraScan Duo
The new Photo Research PR-680 SpectraScan Duo combines the
color accuracy of a spectroradiometer with the sensitivity and speed of a photometer.
This is achieved by integrating a 256 sensor linear diode array spectroradiometer
with a PMT-based photometer - all in a single battery-powered hand-held instrument.
Features include a high-resolution touch-screen color display, four automated apertures,
USB and Bluetooth connectivity, and SD measurement storage.

LR-127 LED Analyzer for PR-650,
PR-705/715 and PR-880
The LR-127 is an optical accessory designed to measure discrete
(3 mm or 5 mm packages) LEDs for parameters recommeded by CIE 127 Technical Report
- Measurement of LEDs. Per this report the average luminous intensity (candelas)
of the LED is determined by making two measurements - one measurement is made at
a 2° cone (Condition A) and the second through a 6.5° cone (Condition B). The two
readings are then averaged.
The LR-127 makes both measurements simply by sliding a lever
to the A or B position. This means that the user does not have to change accessories
to make both measurements.
